Abstract
The utility model discloses a drill bit for a wind coal drill. The drill bit comprises a drill bit body with a middle I (2) and a middle II (3). The middle I (2) and the middle II (3) are distributed in a stepped mode, the drill bit body is installed and clamped in a clamp of the wind coal drill through the middle I (2) and the middle II (3), the contact area of the drill bit body and the clamp of the wind coal drill is increased, and the phenomenon that clamping is conducted only through the drill bit body and the clamp of the wind coal drill in the prior art is changed, so that the drill bit for the wind coal drill is suitable for the wind coal drill and improves the clamping force of the drill bit body.
Description
One, technical field
The utility model relates to a kind of drill bit, especially a kind of drill bit for wind coal borer.
Two, background technology
In the working surface production process of mine district, as the end cap screw eye of coal-winning machine damages, the perforation of plant equipment needs reaming, for ensureing working well of plant equipment, often need to carry out drilling operation, and under mine, ban use of electric drill, can only use wind coal borer, therefore the drill bit for wind coal borer is a kind of important mining equiment, at the existing drill bit for wind coal borer, also there is no a kind of drill bit for wind coal borer that is applicable to various operations.
Three, summary of the invention
In order to overcome above-mentioned technical disadvantages, the purpose of this utility model is to provide a kind of drill bit for wind coal borer, is therefore applicable to wind coal borer and uses, and has improved the chucking power of drill body.
For achieving the above object, the technical scheme that the utility model is taked is: include the drill body with I in Central and middle part II, I in Central and middle part II are set to step and distribute.
I in Central and middle part II are arranged in the fixture of wind coal borer, start wind coal borer, drive drill body to carry out bore operation, owing to having designed I in Central and middle part II, by I in Central and middle part II drill body clamping in the fixture of wind coal borer, increased the contact area of the fixture of drill body and wind coal borer, no longer just the fixture by drill body and wind coal borer carries out clamping, therefore be applicable to wind coal borer and use, improved the chucking power of drill body.
The utility model has designed, drill body is set to also include front portion, rear portion and latch, front portion, I in Central, middle part II and rear portion are set to be coupled to each other successively, on front portion, be provided with blade, I in Central and middle part II are set to cylinder, rear portion is set to bullet, is provided with latch latch and is set to the circumferential distribution along I in Central on I in Central.
The utility model has designed, and the outline line of the lateral surface at the position, rear end at fore drill bit position is set to meander line.
The utility model has designed, and the tapering of the bullet at rear portion is set to 13-21 °.
The utility model has designed, and the tapering of the bullet at rear portion is set to 18.2 °.
In the technical program, I in Central and the middle part II with step distribution are important technical characterictic, in the technical field of the drill bit for wind coal borer, have novelty, creativeness and practicality.
Four, accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
Five, the specific embodiment
Fig. 1 is first embodiment of the present utility model, illustrate by reference to the accompanying drawings the present embodiment, include front portion 1, I in Central 2, middle part II 3, rear portion 4 and latch 5, front portion 1, I in Central 2, middle part II 3 and rear portion 4 are set to be coupled to each other successively, on anterior 1, be provided with blade, I in Central 2 and middle part II 3 are set to cylinder I in Central 2 and middle part II 3 and are set to step distribution, rear portion 4 is set to bullet, is provided with latch 5 latch 5 and is set to along the circumferential distribution of I in Central 2 on I in Central 2.
In the present embodiment, the outline line at the lateral surface at the position, rear end at anterior 1 drill bit position is set to meander line.
In the present embodiment, the tapering of the bullet at rear portion 4 is set to 13 °.
I in Central 2, middle part II 3 and rear portion 4 are arranged in the fixture of wind coal borer, and the fixture clamping latch 5 with wind coal borer, acts on front portion 1 and need to punch on position, starts wind coal borer, drives anterior 1 to carry out bore operation.
Second embodiment of the present utility model, the tapering of the bullet at rear portion 4 is set to 21 °.
The 3rd embodiment of the present utility model, the tapering of the bullet at rear portion 4 is set to 17 °.
The 4th embodiment of the present utility model, the tapering of the bullet at rear portion 4 is set to 18.2 °.Through overtesting, the present embodiment bores the hole of wooden thing, and its effect is best.
The utlity model has lower feature:
1, owing to having designed I in Central 2 and middle part II 3, by I in Central 2 and middle part II 3 drill body clamping in the fixture of wind coal borer, increased the contact area of the fixture of drill body and wind coal borer, no longer just the fixture by drill body and wind coal borer carries out clamping, therefore be applicable to wind coal borer and use, improved the chucking power of drill body.
2, owing to having designed front portion 1, to the boring better effects if of spongiosa thing, drilling efficiency is higher.
3, owing to having designed front portion 1, I in Central 2, middle part II 3, rear portion 4 and latch 5, by the effect of latch 5, connect more firm with the fixture of wind coal borer.
In the bit technique field for wind coal borer; Every drill body with I in Central 2 and middle part II 3 that includes, I in Central 2 and middle part II 3 are set to the technology contents of step distribution all in protection domain of the present utility model.
